RE-NEET 2024 Physics RL Circuits MCQ Question
Type: MCQ-numerical-Medium-Class 12
The amplitude of the charge oscillating in a circuit decreases exponentially as Q = Q₀e⁻ᴿᵗ/²ᴸ, where Q₀ is the charge at t = 0s. The time at which charge amplitude decreases to 0.50 Q₀ is nearly: [Given that R = 1.5 Ω, L = 12 mH, ln(2) = 0.693]
A
19.01 ms
B
11.09 ms
C
19.01 s
D
11.09 s
Correct Answer
Option B
Detailed Explanation
Using the formula for exponential decay, set Q = 0.5 Q₀ and solve for t using the given values of R and L.
